I wrote that the the BIOS doesn't know about the CF card, so I thought it
is obvious that grub won't know about it either ;)

I never said that I expect this nor did I say that it does not boot; as I
wrote, I boot from the *internal hard drive* and want then the kernel to
find the CF card. This is very similar to a setup I had a couple of years
ago on a machine with 20 GB hard disk limit. There I connected a 250 GB
HDD as secondary master and a smaller HDD containing a /boot partition as
primary master; then I had to *disable* the secondary master drive in the
BIOS so neither the BIOS nor grub knew about the 250 GB HDD, but it was
no problem for the linux kernel to find it and use it as / . So where /
lies is not grub's business at all, but the kernel's.

Thanks.
